In a clinical trial I, a Drug X was tested with placebo and it was found to be better than the placebo with a p< 0.05. In clinical trial II, a Drug Y was tested with placebo and it was found to be better than the placebo with a p < 0.01. Which of the following statement is correct: Drug Y is better than drug X We can say with more confidence that drug Y is better than the placebo Drug X is effective 95% of the time and Drug Y is effective 99% of the time Drug X fails in the treatment 5% of the time

The effectiveness of S was greater than that of Q.If the above statements are true, which of the following must also be true ?A P and S were equally effective B P was the most effective C S was the most effective D R was less effective than P

When looking at the percentage of patients whose symptoms were relieved after taking a placebo, a scientist sees a 20% success rate. The success rate of patients whose symptoms were relieved after taking a new composite drug was 30%. The scientist determines that the margin of error is 10%, which indicates that the new drug had no statistically significant positive effect. In which stage of the engineering process is this scientist?A.Looking for future improvementsB.Evaluating test resultsC.Identifying a needD.ScreeningSUBMITarrow_backPREVIOUS
